DETAILED DESCRIPTION Example Mobile Device

FIG. 1 is a block diagram of an example mobile device 100. The mobiledevice 100 can be, for example, a handheld computer, a personal digitalassistant, a cellular telephone, a network appliance, a camera, a smartphone, an enhanced general packet radio service (EGPRS) mobile phone, anetwork base station, a media player, a navigation device, an emaildevice, a game console, or a combination of any two or more of thesedata processing devices or other data processing devices.

Mobile Device Overview

In some implementations, the mobile device 100 includes atouch-sensitive display 102. The touch-sensitive display 102 canimplement liquid crystal display (LCD) technology, light emittingpolymer display (LPD) technology, or some other display technology. Thetouch sensitive display 102 can be sensitive to haptic and/or tactilecontact with a user.

In some implementations, the touch-sensitive display 102 can comprise amulti-touch-sensitive display 102. A multi-touch-sensitive display 102can, for example, process multiple simultaneous touch points, includingprocessing data related to the pressure, degree, and/or position of eachtouch point. Such processing facilitates gestures and interactions withmultiple fingers, chording, and other interactions. Othertouch-sensitive display technologies can also be used, e.g., a displayin which contact is made using a stylus or other pointing device. Someexamples of multi-touch-sensitive display technology are described inU.S. Pat. Nos. 6,323,846, 6,570,557, 6,677,932, and 6,888,536, each ofwhich is incorporated by reference herein in its entirety.

In some implementations, the mobile device 100 can display one or moregraphical user interfaces on the touch-sensitive display 102 forproviding the user access to various system objects and for conveyinginformation to the user. In some implementations, the graphical userinterface can include one or more display objects 104, 106. In theexample shown, the display objects 104, 106, are graphic representationsof system objects. Some examples of system objects include devicefunctions, applications, windows, files, alerts, events, or otheridentifiable system objects.

Example Mobile Device Functionality

In some implementations, the mobile device 100 can implement multipledevice functionalities, such as a telephony device, as indicated by aphone object 110; an e-mail device, as indicated by the e-mail object112; a network data communication device, as indicated by the Web object114; a Wi-Fi base station device (not shown); and a media processingdevice, as indicated by the media player object 116. In someimplementations, particular display objects 104, e.g., the phone object110, the e-mail object 112, the Web object 114, and the media playerobject 116, can be displayed in a menu bar 118. In some implementations,device functionalities can be accessed from a top-level graphical userinterface, such as the graphical user interface illustrated in FIG. 1.Touching one of the objects 110, 112, 114, or 116 can, for example,invoke corresponding functionality.

In some implementations, the mobile device 100 can implement networkdistribution functionality. For example, the functionality can enablethe user to take the mobile device 100 and provide access to itsassociated network while traveling. In particular, the mobile device 100can extend Internet access (e.g., Wi-Fi) to other wireless devices inthe vicinity. For example, mobile device 100 can be configured as a basestation for one or more devices. As such, mobile device 100 can grant ordeny network access to other wireless devices.

In some implementations, upon invocation of device functionality, thegraphical user interface of the mobile device 100 changes, or isaugmented or replaced with another user interface or user interfaceelements, to facilitate user access to particular functions associatedwith the corresponding device functionality. For example, in response toa user touching the phone object 110, the graphical user interface ofthe touch-sensitive display 102 may present display objects related tovarious phone functions; likewise, touching of the email object 112 maycause the graphical user interface to present display objects related tovarious e-mail functions; touching the Web object 114 may cause thegraphical user interface to present display objects related to variousWeb-surfing functions; and touching the media player object 116 maycause the graphical user interface to present display objects related tovarious media processing functions.

In some implementations, the top-level graphical user interfaceenvironment or state of FIG. 1 can be restored by pressing a button 120located near the bottom of the mobile device 100. In someimplementations, each corresponding device functionality may havecorresponding “home” display objects displayed on the touch-sensitivedisplay 102, and the graphical user interface environment of FIG. 1 canbe restored by pressing the “home” display object.

In some implementations, the top-level graphical user interface caninclude additional display objects 106, such as a short messagingservice (SMS) object 130, a calendar object 132, a photos object 134, acamera object 136, a calculator object 138, a stocks object 140, aweather object 142, a maps object 144, a notes object 146, a clockobject 148, an address book object 150, and a settings object 152.Touching the SMS display object 130 can, for example, invoke an SMSmessaging environment and supporting functionality; likewise, eachselection of a display object 132, 134, 136, 138, 140, 142, 144, 146,148, 150, and 152 can invoke a corresponding object environment andfunctionality.

Additional and/or different display objects can also be displayed in thegraphical user interface of FIG. 1. For example, if the device 100 isfunctioning as a base station for other devices, one or more“connection” objects may appear in the graphical user interface toindicate the connection. In some implementations, the display objects106 can be configured by a user, e.g., a user may specify which displayobjects 106 are displayed, and/or may download additional applicationsor other software that provides other functionalities and correspondingdisplay objects.

In some implementations, the mobile device 100 can include one or moreinput/output (I/O) devices and/or sensor devices. For example, a speaker160 and a microphone 162 can be included to facilitate voice-enabledfunctionalities, such as phone and voice mail functions. In someimplementations, an up/down button 184 for volume control of the speaker160 and the microphone 162 can be included. The mobile device 100 canalso include an on/off button 182 for a ring indicator of incoming phonecalls. In some implementations, a loud speaker 164 can be included tofacilitate hands-free voice functionalities, such as speaker phonefunctions. An audio jack 166 can also be included for use of headphonesand/or a microphone.

In some implementations, a proximity sensor 168 can be included tofacilitate the detection of the user positioning the mobile device 100proximate to the user's ear and, in response, to disengage thetouch-sensitive display 102 to prevent accidental function invocations.In some implementations, the touch-sensitive display 102 can be turnedoff to conserve additional power when the mobile device 100 is proximateto the user's ear.

Other sensors can also be used. For example, in some implementations, anambient light sensor 170 can be utilized to facilitate adjusting thebrightness of the touch-sensitive display 102. In some implementations,an accelerometer 172 can be utilized to detect movement of the mobiledevice 100, as indicated by the directional arrow 174. Accordingly,display objects and/or media can be presented according to a detectedorientation, e.g., portrait or landscape. In some implementations, themobile device 100 includes circuitry and sensors for supporting alocation determining capability, such as that provided by the globalpositioning system (GPS) or other positioning systems (e.g., systemsusing Wi-Fi access points, television signals, cellular grids, UniformResource Locators (URLs)). In some implementations, a positioning system(e.g., a GPS receiver) can be integrated into the mobile device 100 orprovided as a separate device that can be coupled to the mobile device100 through an interface (e.g., port device 190) to provide access tolocation-based services. In some implementations, the mobile device 100includes a gyroscopic sensor or other sensors that can be used to detectmotion of the device.

In some implementations, a port device 190, e.g., a Universal Serial Bus(USB) port, or a docking port, or some other wired port connection, canbe included. The port device 190 can, for example, be utilized toestablish a wired connection to other computing devices, such as othercommunication devices 100, network access devices, a personal computer,a printer, a display screen, or other processing devices capable ofreceiving and/or transmitting data. In some implementations, the portdevice 190 allows the mobile device 100 to synchronize with a hostdevice using one or more protocols, such as, for example, the TCP/IP,HTTP, UDP and any other known protocol. In some implementations, aTCP/IP over USB protocol can be used, as described in U.S. ProvisionalPatent Application No. 60/945,904, filed Jun. 22, 2007, for “MultiplexedData Stream Protocol,” which provisional patent application isincorporated by reference herein in its entirety.

The mobile device 100 can also include a camera lens and sensor 180. Insome implementations, the camera lens and sensor 180 can be located onthe back surface of the mobile device 100. The camera can capture stillimages and/or video.

The mobile device 100 can also include one or more wirelesscommunication subsystems, such as an 802.11b/g communication device 186,and/or a Bluetooth™ communication device 188. Other communicationprotocols can also be supported, including other 802.x communicationprotocols (e.g., WiMax, Wi-Fi, 3G), code division multiple access(CDMA), global system for mobile communications (GSM), Enhanced Data GSMEnvironment (EDGE), etc.

Example Mobile Device Architecture

FIG. 2 is a block diagram 200 of an example implementation of the mobiledevice 100 of FIG. 1. The mobile device 100 can include a memoryinterface 202, one or more data processors, image processors and/orcentral processing units 204, and a peripherals interface 206. Thememory interface 202, the one or more processors 204 and/or theperipherals interface 206 can be separate components or can beintegrated in one or more integrated circuits. The various components inthe mobile device 100 can be coupled by one or more communication busesor signal lines.

Sensors, devices, and subsystems can be coupled to the peripheralsinterface 206 to facilitate multiple functionalities. For example, amotion sensor 210, a light sensor 212, and a proximity sensor 214 can becoupled to the peripherals interface 206 to facilitate the orientation,lighting, and proximity functions described with respect to FIG. 1.Other sensors 216 can also be connected to the peripherals interface206, such as a positioning system (e.g., GPS receiver), a temperaturesensor, a biometric sensor, a gyroscope, or other sensing device, tofacilitate related functionalities.

A camera subsystem 220 and an optical sensor 222, e.g., a chargedcoupled device (CCD) or a complementary metal-oxide semiconductor (CMOS)optical sensor, can be utilized to facilitate camera functions, such asrecording photographs and video clips.

Communication functions can be facilitated through one or more wirelesscommunication subsystems 224, which can include radio frequencyreceivers and transmitters and/or optical (e.g., infrared) receivers andtransmitters. The specific design and implementation of thecommunication subsystem 224 can depend on the communication network(s)over which the mobile device 100 is intended to operate. For example, amobile device 100 may include communication subsystems 224 designed tooperate over a GSM network, a GPRS network, an EDGE network, a Wi-Fi orWiMax network, and a Bluetooth™ network. In particular, the wirelesscommunication subsystems 224 may include hosting protocols such that thedevice 100 may be configured as a base station for other wirelessdevices.

The I/O subsystem 240 can include a touch screen controller 242 and/orother input controller(s) 244. The touch-screen controller 242 can becoupled to a touch screen 246. The touch screen 246 and touch screencontroller 242 can, for example, detect contact and movement or breakthereof using any of a plurality of touch sensitivity technologies,including but not limited to capacitive, resistive, infrared, andsurface acoustic wave technologies, as well as other proximity sensorarrays or other elements for determining one or more points of contactwith the touch screen 246.

The other input controller(s) 244 can be coupled to other input/controldevices 248, such as one or more buttons, rocker switches, thumb-wheel,infrared port, USB port, and/or a pointer device such as a stylus. Theone or more buttons (not shown) can include an up/down button for volumecontrol of the speaker 228 and/or the microphone 230.

In one implementation, a pressing of the button for a first duration maydisengage a lock of the touch screen 246; and a pressing of the buttonfor a second duration that is longer than the first duration may turnpower to the mobile device 100 on or off. The user may be able tocustomize a functionality of one or more of the buttons. The touchscreen 246 can, for example, also be used to implement virtual or softbuttons and/or a keyboard.

In some implementations, the mobile device 100 can present recordedaudio and/or video files, such as MP3, AAC, and MPEG files. In someimplementations, the mobile device 100 can include the functionality ofan MP3 player, such as an iPod™. The mobile device 100 may, therefore,include a 36-pin connector that is compatible with the iPod. Otherinput/output and control devices can also be used.

The memory interface 202 can be coupled to memory 250. The memory 250can include high-speed random access memory and/or non-volatile memory,such as one or more magnetic disk storage devices, one or more opticalstorage devices, and/or flash memory (e.g., NAND, NOR). The memory 250can store an operating system 252, such as Darwin, RTXC, LINUX, UNIX, OSX, WINDOWS, or an embedded operating system such as VxWorks. Theoperating system 252 may include instructions for handling basic systemservices and for performing hardware dependent tasks. In someimplementations, the operating system 252 can be a kernel (e.g., UNIXkernel).

The memory 250 may also store communication instructions 254 tofacilitate communicating with one or more additional devices, one ormore computers and/or one or more servers.

The memory 250 may alsostore other software instructions (not shown), such as web videoinstructions to facilitate web video-related processes and functions;and/or web shopping instructions to facilitate web shopping-relatedprocesses and functions. In some implementations, the media processinginstructions 266 are divided into audio processing instructions andvideo processing instructions to facilitate audio processing-relatedprocesses and functions and video processing-related processes andfunctions, respectively. An activation record and International MobileEquipment Identity (IMEI) 274 or similar hardware identifier can also bestored in memory 250.

Each of the above identified instructions and applications cancorrespond to a set of instructions for performing one or more functionsdescribed above. These instructions need not be implemented as separatesoftware programs, procedures, or modules. The memory 250 can includeadditional instructions or fewer instructions. Furthermore, variousfunctions of the mobile device 100 may be implemented in hardware and/orin software, including in one or more signal processing and/orapplication specific integrated circuits.

FIG. 3 illustrates an example process 300 for modifying a graphical userinterface. For convenience, the process 300 is described below inreference to a device (e.g., device 100, 200) that performs the process.

One or more sensors of the device detect motion (e.g., a pattern ofmotion associated with pre-determined motion characteristics) of thedevice (302). One or more sensors on the device 100/200 (e.g.,accelerometer 172, motion sensor 210, proximity sensor 214, othersensors 216, a gyroscope) can detect changes in the orientation,acceleration, proximity, etc. of the device and the degrees of thechanges in orientation, acceleration, proximity, etc. caused by motionof the device and/or a user carrying the device. These changes inorientation, acceleration, proximity, etc. can be interpreted by thedevice as motion of the device. If the changes exhibit regularity orpredictability or match predetermined criteria, the changes can beinterpreted by the device as a pattern of motion. For example, a user ofthe device 100 can be walking and holding the device for use at the sametime. The device 100 can be oscillating (e.g., bouncing up and down) dueto the user walking or running. The oscillation can be detected by thesensors of the device. As another example, a user of the device 100 canbe a passenger in an automobile and holding the device for use while theautomobile is moving. The device 100 can be bouncing up and down as aresult, which can be detected by the sensors of the device.

The motion of the device and/or the user can affect the user's accuracywhen attempting to interact with a graphical user interface that isdisplayed on the touch-sensitive display of the device. For example,returning to the above example of the user carrying and using the devicewhile walking, the device can bounce up and down due to motion of thecarrying hand and arm while the user is walking. The bouncing can causethe user to touch the touch-sensitive display at an unintended locationand select a user interface element that the user did not intend toselect.

To address the problem described above, the detected pattern of devicemotion is mapped to one or more adjustments to the graphical userinterface (304), and the graphical user interface of the device isadjusted using the mapped adjustments (306). The pattern of motiondetected by the sensors is mapped to one or more adjustments of thegraphical user interface of the device, including user interfaceelements in the graphical user interface, based on one or more criteriarelated to the detected pattern of motion. The criteria can include thetype of the detected motion and the magnitude of the motion. The mappedadjustments are applied to the graphical user interface. The adjustmentscan mitigate the loss in accuracy in the user's attempts to select userinterface elements in the graphical user interface by touching thetouch-sensitive display. In some implementations, the mapping andadjustments can be made by the sensor processing instructions 258 andthe GUI adjustment instructions 273, respectively.

In some implementations, the device 100 can include a user-settableoption to toggle the feature of adjustments to the graphical userinterface based on detected device motion. That is, if the feature isdisabled, no adjustments are made to the graphical user interface basedon detected motion. If the feature is enabled, adjustments can be madeto the graphical user interface based on detected motion.

In some implementations, the adjustment includes resizing of userinterface elements and their corresponding touch areas (e.g., the areaon the touch-sensitive display where a touch on the display selects theuser interface element) in the graphical user interface. For example,rows corresponding to entries in a list interface (e.g., a list ofcontacts in a contact list where a row corresponds to a contact in thelist, a list of media items where a row corresponds to a media item inthe list, etc.) can be enlarged by increasing the height of each of theentry rows. The touch area corresponding to each one of the enlargedrows is also enlarged as a result. The enlarging gives the user a largertarget touch area for a row, lessening the likelihood of unintentionalselections. An example of the enlarging of rows corresponding to entriesin a list is described below in reference to FIGS. 4A-4B.

As another example, the display objects 104 or 106 can be resized. Oneor more of the display objects 104, 106 and their corresponding touchareas can be enlarged, increasing the target touch area for each of theresized display objects. An example of the enlarging of the displayobjects is described below in reference to FIGS. 5A-5B.

In some implementations, the adjustment includes a shift of thegraphical user interface or of user interface elements in the graphicaluser interface. The graphical user interface/user interface elements canbe shifted vertically and/or horizontally. In some implementations, theshift is in a direction opposite to the detected motion of the device;the shift attempts to relocate a user interface element to a position onthe touch-sensitive display that the user is likely to touch if the userintended to select the user interface element in view of the motion ofthe device. An example of the shifting of user interface elements isdescribed below in reference to FIG. 6.

In some implementations, the adjustment includes changing a sensitivitylevel of the touch-sensitive display. For example, the sensitivity levelof the touch-sensitive display can be decreased. Decreasing thesensitivity level of the touch-sensitive display increases the pressureneeded for a touch on the touch-sensitivity display to be recognized bythe device. The increase in required pressure to select a user interfaceelement can lead the user to be more deliberate in their attempts totouch the touch-sensitive display to select user interface elements.

In some implementations, the adjustment includes adjusting the targettouch area of a user interface element based on an angle at which thedevice is being held. For example, if the device is held at an angledeviating from a default angle and which is more parallel thanperpendicular with the ground, the target touch area of a user interfaceelement can be enlarged. Optionally, the target touch area can also beskewed to account for the angle.

In some implementations, the adjustment includes enlarging some targettouch areas and/or user interface elements relative to others. Forexample, a fisheye effect can be imposed on the target touch areas andthe user interface to enlarge the elements and target areas nearer tothe center of the “fisheye” relative to elements and target areas nearerto the periphery. The center of the “fisheye” need not be the center ofthe display; the center of the “fisheye” can be positioned over userinterface elements in the user interface that are selected more often orare considered more important.

While several types of adjustments are described above, it should beappreciated that the adjustment to the graphical user interface made bythe device can include any combination of the described types ofadjustments and other suitable types of adjustments.

In some implementations, the amount of an adjustment is a predefinedamount or percentage. For example, a user interface element can beresized by a predetermined amount of pixels or a predeterminedpercentage of the original size of the user interface element. In someother implementations, the amount of an adjustment is based on theamount of detected motion, amount of detected acceleration, amount ofchange in orientation from a starting position, or the like. Forexample, if the amount of acceleration from rest is small, the amount ofthe resizing or shifting of a user interface element is small as well.In some implementations, the amount of adjustment can be based on userpreferences. For example, the user can configure (in a device optionsand settings interface, for example) a maximum allowable amount (e.g., apercentage) for a type of adjustment.

In some implementations, the adjustment includes interrupting actionsinitiated by the user with additional confirmation steps. Rather thanshifting or resizing user interface elements by some amount, forexample, the device can add confirmation dialogs or question interfacesto the user interface flow for particular actions and optionally alsoshift or resize user interface elements by a smaller amount. As anexample, if a user attempts to make a call on device 100 while walkingand a bouncing motion of the device is detected, the device 100 candisplay a confirmation dialog box displaying the contact or phone numberto be dialed and asking the user to confirm that the contact or numberthat is displayed is the one to be called. The confirmation dialog boxcan have relatively large target touch areas for “Yes” and “No” buttonsfor the user to select to confirm or decline the call.

In some implementations, the device “learns” particular characteristicsof the motion of the device and the user's interactions with the devicein light of the motion of the device. For example, the device canmeasure magnitudes of the motion of the device due to the user'smotions. As another example, the device can detect the user's mistakesin the selection of user interface elements (e.g., the userunintentionally selects a display object 104 or 106 and then quicklyexits from the application corresponding to the selected displayobject). From the user mistakes, the device can look for patterns in theuser's mistakes (e.g., user is consistently touching one side of thedisplay but intended to touch the other side, the user is missing theirintended targets in a consistent manner, etc.). From this learnedinformation, the device can predict where the user will touch thetouch-sensitive display while the device in motion and make theadjustments to the graphical user interface based on the predictions.

In some implementations, the device detects a motion of the device andcompares the detected motion to one or more predetermined signatures ofmotion. The device can store multiple signatures of motion (e.g., asignature of a bouncing motion while the user is walking, a signature ofa change in orientation, etc.) and, for each signature, correspondingadjustments to the graphical user interface. If the detected motionmatches one of the predetermined signatures, the device adjusts thegraphical user interface using the adjustments corresponding to thematching signature. In some other implementations, the device comparesthe detected motion and compares the detected motion to the signatures.The device uses the comparison to determine which signature is closestto the detected motion and applies the graphical user interfaceadjustments corresponding to the signature determined to be closest tothe detected motion.

FIGS. 4A and 4B illustrate an example contact list user interface on anexample mobile device. FIG. 4A illustrates device 100 with a contactlist 400 displayed on the display 102. The contact list application 400includes one or more contacts 402A, with a row in the contact list 400for each contact 402A. A row 402A can have a height H 406. A user cantouch the display 102 on the area of a contact 402A to display thecontact information for that contact. For example, if the user wishes toview the contact information for “John Adams,” the user touches thedisplay over the area of the row for the contact “John Adams.” A toolbar404 with buttons for various features related to phone functionality canalso be displayed. Example features related to phone functionality caninclude a list of favorite contacts, a contact list, a log of recentcalls, a keypad, and voicemail.

While the device is moving, the motion of the device can be detected.The device can change the size of the rows of the contacts in thecontact list application 400 to give the user a larger target area foreach contact. For example, the height of a row can be increased. Asshown in FIG. 4B, the contact list application 400 has contacts 402Bwhich are located in rows whose heights have been increased to 2×H 408.This gives the user a larger touch area with which to select a contact.In some implementations, the height of the toolbar 404 can be increasedas well.

FIGS. 5A and 5B illustrate an example user interface of a device. InFIG. 5A, the device 101 is displaying display objects 104A (objects124A, 125A, 134A, 126A) and 106A (objects 114A, 123A, 132A, 150A, 148A,138A, 152A) at their original sizes on the touch-sensitive display 102.A display object 104A or 106A can have, for example, a width W 502. Theobjects 104A and 106A can be resized in response to motion of the devicethat is detected by one or more sensors on the device. FIG. 5B shows thedevice 101 with the resized objects 104B (objects 124B, 125B, 134B,126B) and 106B (objects 114B, 123B, 132B, 150B, 148B, 138B, 152B). Theresized objects 104B, 106B are larger (e.g., have a width of 1.25×W 504)than the original size objects 104A and 106A and has larger target touchareas than the original size objects 104A and 106A. This gives the usera larger touch area with which to select a display object 104B or 106B.

FIG. 6 illustrates device 101 with a graphical user interface thatincludes display objects 106. In FIG. 6, the display objects 106 areshifted, compared to the display objects 106 in FIG. 1B, verticallydownward by a distance D 602 toward the bottom of the graphical userinterface. The shift moves the target touch areas of the display objects106 to a different position. In some implementations, the new positionis a predetermined distance from the original position. In some otherimplementations, the new position is determined by the device based on aprediction of where the user will touch the touch-sensitive display ifthe user wanted to select the user interface element while the device isin motion.
